exotics don't sell out as fast as regular items b/c they are usually much higher in price than traditional leathers, some people are offended by them and won't purchase, and other people - like you - just aren't overly sure what they are all about and how they will wear over time. exotics are much more delicate than any leathers - the exceptions are ostrich and stringray. if you're a complete newbie to exotics start with something ostrich because they are VERY hard-wearing and can suffer lots of damage and abuse. i have a lot of ostrich stuff and love it. python (like the Prada one you showed) would be one to avoid - i have a python item but they don't wear well (scales lift and they can look worn out even when only used minimally). my exotics are all pre-loved only, i don't feel good buying these items new for animal rights reasons but if they are already out there in the world i'm ok with it. the pre-loved market is a good place to look and get lower prices if you want to try an exotic piece without the super high original retail prices
